The 327c478bd9Sstevel@tonic-gate * notes don't go into any real detail, and the viewer of this file is 337c478bd9Sstevel@tonic-gate * encouraged to look at the code and its associated comments to better 347c478bd9Sstevel@tonic-gate * understand inetd's operation. This saves the potential for the code 357c478bd9Sstevel@tonic-gate * and these notes diverging over time. 367c478bd9Sstevel@tonic-gate * 377c478bd9Sstevel@tonic-gate * Inetd's major work is done from the context of event_loop(). Within this 387c478bd9Sstevel@tonic-gate * loop, inetd polls for events arriving from a number of different file 397c478bd9Sstevel@tonic-gate * descriptors, representing the following event types, and initiates 407c478bd9Sstevel@tonic-gate * any necessary event processing: 417c478bd9Sstevel@tonic-gate * - incoming network connections/datagrams. 427c478bd9Sstevel@tonic-gate * - notification of terminated processes (discovered via contract events). 437c478bd9Sstevel@tonic-gate * - instance specific events originating from the SMF master restarter. 447c478bd9Sstevel@tonic-gate * - stop/refresh requests from the inetd method processes (coming in on a 457c478bd9Sstevel@tonic-gate * Unix Domain socket). 467c478bd9Sstevel@tonic-gate * There's also a timeout set for the poll, which is set to the nearest 477c478bd9Sstevel@tonic-gate * scheduled timer in a timer queue that inetd uses to perform delayed 487c478bd9Sstevel@tonic-gate * processing, such as bind retries. 497c478bd9Sstevel@tonic-gate * The SIGHUP and SIGINT signals can also interrupt the poll, and will 507c478bd9Sstevel@tonic-gate * result in inetd being refreshed or stopped respectively, as was the 517c478bd9Sstevel@tonic-gate * behavior with the old inetd. 527c478bd9Sstevel@tonic-gate * 537c478bd9Sstevel@tonic-gate * Inetd implements a state machine for each instance. The states within the 547c478bd9Sstevel@tonic-gate * machine are: offline, online, disabled, maintenance, uninitialized and 557c478bd9Sstevel@tonic-gate * specializations of the offline state for when an instance exceeds one of 567c478bd9Sstevel@tonic-gate * its DOS limits. The state of an instance can be changed as a 577c478bd9Sstevel@tonic-gate * result/side-effect of one of the above events occurring, or inetd being 587c478bd9Sstevel@tonic-gate * started up. The ongoing state of an instance is stored in the SMF 597c478bd9Sstevel@tonic-gate * repository, as required of SMF restarters. This enables an administrator 607c478bd9Sstevel@tonic-gate * to view the state of each instance, and, if inetd was to terminate 617c478bd9Sstevel@tonic-gate * unexpectedly, it could use the stored state to re-commence where it left off. 627c478bd9Sstevel@tonic-gate * 637c478bd9Sstevel@tonic-gate * Within the state machine a number of methods are run (if provided) as part 647c478bd9Sstevel@tonic-gate * of a state transition to aid/ effect a change in an instance's state. The 657c478bd9Sstevel@tonic-gate * supported methods are: offline, online, disable, refresh and start. The 667c478bd9Sstevel@tonic-gate * latter of these is the equivalent of the server program and its arguments 677c478bd9Sstevel@tonic-gate * in the old inetd. 687c478bd9Sstevel@tonic-gate * 697c478bd9Sstevel@tonic-gate * Events from the SMF master restarter come in on a number of threads 707c478bd9Sstevel@tonic-gate * created in the registration routine of librestart, the delegated restarter 717c478bd9Sstevel@tonic-gate * library. These threads call into the restart_event_proxy() function 727c478bd9Sstevel@tonic-gate * when an event arrives. To serialize the processing of instances, these events 737c478bd9Sstevel@tonic-gate * are then written down a pipe to the process's main thread, which listens 747c478bd9Sstevel@tonic-gate * for these events via a poll call, with the file descriptor of the other 757c478bd9Sstevel@tonic-gate * end of the pipe in its read set, and processes the event appropriately. 767c478bd9Sstevel@tonic-gate * When the event has been processed (which may be delayed if the instance 777c478bd9Sstevel@tonic-gate * for which the event is for is in the process of executing one of its methods 787c478bd9Sstevel@tonic-gate * as part of a state transition) it writes an acknowledgement back down the 797c478bd9Sstevel@tonic-gate * pipe the event was received on. The thread in restart_event_proxy() that 807c478bd9Sstevel@tonic-gate * wrote the event will read the acknowledgement it was blocked upon, and will 817c478bd9Sstevel@tonic-gate * then be able to return to its caller, thus implicitly acknowledging the 827c478bd9Sstevel@tonic-gate * event, and allowing another event to be written down the pipe for the main 837c478bd9Sstevel@tonic-gate * thread to process. 847c478bd9Sstevel@tonic-gate */ 857c478bd9Sstevel@tonic-gate 867c478bd9Sstevel@tonic-gate 877c478bd9Sstevel@tonic-gate #include <netdb.h> 887c478bd9Sstevel@tonic-gate #include <stdio.h> 89004388ebScasper #include <stdio_ext.h> 907c478bd9Sstevel@tonic-gate #include <stdlib.h> 917c478bd9Sstevel@tonic-gate #include <strings.h> 927c478bd9Sstevel@tonic-gate #include <unistd.h> 937c478bd9Sstevel@tonic-gate #include <assert.h> 947c478bd9Sstevel@tonic-gate #include <sys/types.h> 957c478bd9Sstevel@tonic-gate #include <sys/socket.h> 967c478bd9Sstevel@tonic-gate #include <netinet/in.h> 977c478bd9Sstevel@tonic-gate #include <fcntl.h> 987c478bd9Sstevel@tonic-gate #include <signal.h> 997c478bd9Sstevel@tonic-gate #include <errno.h> 1007c478bd9Sstevel@tonic-gate #include <locale.h> 1017c478bd9Sstevel@tonic-gate #include <syslog.h> 1027c478bd9Sstevel@tonic-gate #include <libintl.h> 1037c478bd9Sstevel@tonic-gate #include <librestart.h> 1047c478bd9Sstevel@tonic-gate #include <pthread.h> 1057c478bd9Sstevel@tonic-gate #include <sys/stat.h> 1067c478bd9Sstevel@tonic-gate #include <time.h> 1077c478bd9Sstevel@tonic-gate #include <limits.h> 1087c478bd9Sstevel@tonic-gate #include <libgen.h> 1097c478bd9Sstevel@tonic-gate #include <tcpd.h> 1107c478bd9Sstevel@tonic-gate #include <libscf.h> 1117c478bd9Sstevel@tonic-gate #include <libuutil.h> 1127c478bd9Sstevel@tonic-gate #include <stddef.h> 1137c478bd9Sstevel@tonic-gate #include <bsm/adt_event.h> 1147cd7ea0bSrs #include <ucred.h> 1157c478bd9Sstevel@tonic-gate #include "inetd_impl.h" 1167c478bd9Sstevel@tonic-gate 1177c478bd9Sstevel@tonic-gate /* path to inetd's binary */ 1187c478bd9Sstevel@tonic-gate #define INETD_PATH "/usr/lib/inet/inetd" 1197c478bd9Sstevel@tonic-gate 1207c478bd9Sstevel@tonic-gate /* 1217c478bd9Sstevel@tonic-gate * inetd's default configuration file paths. /etc/inetd/inetd.conf is set 1227c478bd9Sstevel@tonic-gate * be be the primary file, so it is checked before /etc/inetd.conf. 1237c478bd9Sstevel@tonic-gate */ 1247c478bd9Sstevel@tonic-gate #define PRIMARY_DEFAULT_CONF_FILE "/etc/inet/inetd.conf" 1257c478bd9Sstevel@tonic-gate #define SECONDARY_DEFAULT_CONF_FILE "/etc/inetd.conf" 1267c478bd9Sstevel@tonic-gate 1277c478bd9Sstevel@tonic-gate /* Arguments passed to this binary to request which method to execute. */ 1287c478bd9Sstevel@tonic-gate #define START_METHOD_ARG "start" 1297c478bd9Sstevel@tonic-gate #define STOP_METHOD_ARG "stop" 1307c478bd9Sstevel@tonic-gate #define REFRESH_METHOD_ARG "refresh" 1317c478bd9Sstevel@tonic-gate 1327c478bd9Sstevel@tonic-gate /* connection backlog for unix domain socket */ 1337c478bd9Sstevel@tonic-gate #define UDS_BACKLOG 2 1347c478bd9Sstevel@tonic-gate 1357c478bd9Sstevel@tonic-gate /* number of retries to recv() a request on the UDS socket before giving up */ 1367c478bd9Sstevel@tonic-gate #define UDS_RECV_RETRIES 10 1377c478bd9Sstevel@tonic-gate 1387c478bd9Sstevel@tonic-gate /* enumeration of the different ends of a pipe */ 1397c478bd9Sstevel@tonic-gate enum pipe_end { 1407c478bd9Sstevel@tonic-gate PE_CONSUMER, 1417c478bd9Sstevel@tonic-gate PE_PRODUCER 1427c478bd9Sstevel@tonic-gate };
